Code 5005 in 1961 Commercial is called Romany Red. The Dupont mix code is DUR-1114-H. The swatch shows it to be a very deep red almost like a deep wine colour.
Interesting that GM used the same number sequence year to year during this era but changed the colour.
In 1959 code 5005 = Sherwood green
In 1960 code 5005 = Grenadier Red which is a more distinct red
In 1962 code 5005 = Sea Mist Jade Metallic
